Hello, I'm having a problem calculating the final pressure before condenser. I'm calculating the pressure that builds up in a system that at the beginning has atmospheric pressure @ T=20C and is introduced with 1 mole/second of CO2(44.01g/mol) @ T=60C and 0.318 mole/second of CH2Cl2(84,93 g/mol) @ T=60C. The volume of the system is 80 m3. There is an outlet after the condenser. The amount of gases that enters the system must exit trough the condenser. So I think there should be a constant pressure at some point. The process goes for 360 minutes. I have very little understanding of gas mechanics, I would be grateful for ant help.
